CABLE Halvefiizra Specification of Letters Patent.

Application filed February 12, 1917. Serial No. 148,064.

To ZZ 'whom t may concern:

Be it known that I, DIETRICH F. TRACHTE, a citizen of the United States of America, a resident of the cityof St. Louis, State of Missouri, have invented certain new and useful Improvements in Cable-Hangers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to a hanger for suspending a wire cable from a supporting wire. Hangers of the kind to which my invention relates are arranged at frequent intervals along supporting wires to afford eiiicient supporting means for cables which are hung therein, and it is highly important that, if the hangers are not rigidly attached not, so far as I am aware, resulted in theto'the supporting wires, they be so applied to such wires as to prevent slippage thereon in order that they will not become displaced from their intended positions and fail to supportthe cables at the points where they were originally intended to support them.

Attempts have heretofore been made t0 provide open ring hangers having hooks placed in engagement with the supporting wires, the hooks being so formed as to grip the supporting wires and tend to hold the hangers from movement along the supporting wires. Such attempts, however, have production of a hanger of this description which will not slip along a. supporting wire. My invention has for its object to form a double armed cable hanger having hooks, one of which so embraces and grips a supporting wire as to eliminate the slightest slippage of the hanger in either direction longitudinally of the wire.

Figure I is a top view of my hanger applied to a supporting wire.

Fig. II is a side elevation of the parts shown in Fig. I.

Fig. III is an elevation of the hanger viewed in a direction indicated by the arrow crossing the sectional line IIIIII, Fig. II, extending through the supporting wire. Fig. IV is an elevation of the hanger viewed in a direction indicated by the arrow crossing the sectional line IV-IV, Fig. II, extending through the supporting wire. One of my hangers, designated as a whole by the letter A, is shown in the accompany ing drawings applied to a supporting wire B, the loop of the hanger being shown pendant from the supporting wire in the position it occupies when 'a cable is hung therein.

The hanger A isof open ring form and its general contour is that of a circular ring,

except that the arm portions of the hanger are spread laterally away from each other. The hanger, therefore, comprises a loop and arms 1 and 2 diverging from the lower portion- 3 of the loop in opposite directions. The hanger arm l terminates in a hook 4, which may be of any suitable shape or contour which will permit of the hook being applied to the supporting wire that is to receive the attachment of the hanger.

The hanger arm 2 terminates in' a hook C, the inner portion 5 of which is an arcuate extension at the end of said arm 2 and is not offset fromthe general trend of said arm. From the portion 5 the hook extends upwardly and then rearwardly at a distance suhciently removed from the inner portion 5 of the hook to permit of the supporting wire B being seated between the portion 5 and the upper portion of the hook designated 6. The hook portion 6, which is the terminal element of the hook C, extends at a oblique angle to the portion 5 of the hook, as seen in Figs I, II and IV, and therefore does not engage the 'supporting wire B at a point diametrically opposite to that engaged by the inner portion 5 of the hook, but on the contrary the two hook portions engage said wire at opposite sides and at the ends of a line drawn diagonally terminal portion 6 of the hook Cbeing arranged obliquely to the portion 5 of said hook, which causes `the arm 2 of the hanger to be held toward the side of the hanger at which the terminal hook portion 5 is located,

and it is necessary to spring the hanger in the opposite direction in order that the hook 4 may be placed in engagement with the supporting wire. I

' The entire hangen is, therefore, under flo tension when the hook 4 is applied to the supporting Wire and a downward pull is 'exerted upon the last named hook, Which serves not only to hold it firmly in engagement with the supporting Wire but also holds the hook C tightly bound to said Wire. Therefore, inasmuch as the hook C has the two'elements 5 and 6 arranged in gripping engagement With the supporting Wire at points separated from 'each other diagonally of the Wire, any ei'ort to move the hanger longitudinally of the supporting Wire is deeated.

I claim: p

A cable hanger formed from a single piece of spring Wire comprising a cable supporting seat disposed vertically beneath the messenger wireV and transversely thereof to which the hanger is applied, a pair of supporting arms formed integral with the Vertidisposed seat and projecting from the caly sea ,at an angle less than a right angle and extending from themessenger wire to which it is applied in parallel' relations, one of said arms acting as a gripping arm adapted to engage the messenger on its underneath surface, said gripping arm being provided with ahook overlying the messenger Wire and projecting downwardly so that it Will not become disengaged inthe application of the hanger to the messenger,a hook for-med on the other arm adapted to engage the mes senger on its side and top surface, the prong of the last mentioned hook projecting over the messenger and extending in a direction parallel to the arm by Which it is carried, the hooks on the suspension arms being reversely formed and Widely separated and the overlying prongs thereof being arranged at an oblique angle.

In testimony that I claim theforegoing I hereunto aflix my signature.
